Lee's crew must push through waves of mosquitoes and fatigue to finish the deck of their Bulchitna Lake build before the floatplane arrives to take them home for a day of rest. In Haines, Tony and his crew wrestle the largest and heaviest pieces of the build into place without any kind of machinery, and Derek pushes the panic button after more bad weather and mechanical problems delay his build once again.

The drama at Derek's cliffside build near Valdez escalates after rain saturates the region and an accident on the roof almost takes out a crew member. Tony leaves his build in Bobby's hands to tend to another job and returns to find an injury has occurred. Lee discovers the culprit behind a messy footprint while the crew faces sketchy conditions to install the custom windows on their 2500 square foot Bulchitna Lake build.
